Deuteronomy 2:6 In-Context

4 And command the people, You are about to pass through the territory of your brethren the sons of Esau, who live in Se'ir; and they will be afraid of you. So take good heed;
5 do not contend with them; for I will not give you any of their land, no, not so much as for the sole of the foot to tread on, because I have given Mount Se'ir to Esau as a possession.
6 You shall purchase food from them for money, that you may eat; and you shall also buy water of them for money, that you may drink.
7 For the LORD your God has blessed you in all the work of your hands; he knows your going through this great wilderness; these forty years the LORD your God has been with you; you have lacked nothing.'
8 So we went on, away from our brethren the sons of Esau who live in Se'ir, away from the Arabah road from Elath and E'zion-ge'ber. "And we turned and went in the direction of the wilderness of Moab.
